Description
明細書 連続錶造方法および連続錶造装置 技術分野 Description Continuous manufacturing method and continuous manufacturing apparatus
本発明は、 連続錶造方法および連続錶造装置に関する。 連続銬造装置で铸造さ れた薄铸片は後工程の圧延機群でさらに薄く圧延され、 薄板に成形されるが、 踌 造の段階で、 できるだけ銬片を薄くしておくと、 後の圧延工程で工程削減でき、 圧延設備等の設備費を低減できる。 本発明は、 このような薄铸片を铸造するため の連続铸造方法および連続錶造装置に関する。 背景技術 The present invention relates to a continuous manufacturing method and a continuous manufacturing apparatus. The thin piece produced by the continuous production equipment is further thinly rolled by a group of rolling mills in the subsequent process and formed into a thin plate, but at the stage of production, if the thin piece is made as thin as possible, Rolling processes can be reduced, and equipment costs such as rolling equipment can be reduced. The present invention relates to a continuous manufacturing method and a continuous manufacturing apparatus for manufacturing such a thin piece. Background art
連続鐯造装置で薄い铸片を銬造しょうとする場合铸型厚さを薄くすればよいよ うであるが、 銬型厚さは溶鋼を注入するノズルの厚みが制約となるので、 無制限 に薄くすることはできない。 踌型を鎢造方向にほぼ平行な厚みとしたタイプでは 、 9 0腿厚みより薄くなると、 安定的な銬造が困難となるので、 9 0匪が限界で あった。 そこで、 錶型の入側を厚いままにし、 出側に向って絞り、 出側厚さを 12 0 〜5 0丽にしたものもある。 It seems that the thickness of the mold should be reduced when a thin piece is to be manufactured by a continuous manufacturing apparatus.However, the thickness of the mold is unlimited because the thickness of the nozzle for injecting molten steel is limited. It cannot be thinned. In the case of a type having a thickness substantially parallel to the direction of construction, if the thickness is less than 90 thighs, it is difficult to stably produce the type. Therefore, there is a case where the entrance side of the 錶 type is kept thick, and is constricted toward the exit side, and the exit side thickness is set to 120 to 50 丽.
いずれの銬型を用いた場合も、 鎵片を铸型出側厚さより薄くするには、 従来は 、 銬型から引き出された铸片の中に溶鋼が流動している状態で圧下する未凝固圧 下法が用いられていた （従来例 I ) 。 Regardless of which mold is used, in order to make the piece thinner than the mold exit side thickness, conventionally, unsolidification is performed in a state where molten steel flows in the piece drawn from the mold. The rolling method was used (conventional example I).
しかしながら未凝固圧下では長辺側各々 2枚の凝固殻が接合する前に圧下を完 了しなければならないため、 未凝固圧下にて圧下できる銬片厚みは圧下位置での 凝固殻の成長量によって限界がある。 铸片厚みを薄くするためには凝固殻の薄い 間に圧下を完了するよう圧下開始位置を銬型直下へ設置すれば良いが、 铸型直下 で凝固殻を圧下すると錶型冷却板と凝固殻との接触状態に影響を及ぼし凝固不均 一が生じることによりブレークアウトしたり、 表面割れを生じたりする。 また圧 下完了点を上流側にしょうとロール当たりの圧下量を大きくすると内部割れを生 じるため、 圧下量はロール当たり 1 0腿以下で圧下完了点は溶鋼表面より 1900固
以降とする必要がある。 よって、 凝固殻の薄い間に圧下完了させることは現実的 に不可能であり、 十分薄い銬片の連続製造は未だ不可能であった。 However, under non-solidification pressure, the reduction must be completed before the two solidified shells on the long side are joined together, so the reduction can be performed under unsolidified pressure.The thickness of the piece depends on the amount of solidified shell growth at the reduced position. There is a limit.铸 In order to reduce the thickness of the piece, the rolling start position should be set immediately below the mold to complete the reduction while the solidified shell is thin, but if the solidified shell is reduced just below the mold, the cooling plate and solidified shell Influences the state of contact with steel and causes uneven solidification, causing breakouts and surface cracks. In addition, if the rolling completion point is on the upstream side, increasing the rolling reduction per roll will cause internal cracks. Therefore, the rolling reduction is less than 10 thighs per roll and the rolling completion point is 1900 solids from the surface of molten steel. It is necessary to be later. Therefore, it was practically impossible to complete the reduction while the solidified shell was thin, and continuous production of sufficiently thin pieces was still impossible.
一方、 鐯片の未凝固領域ではガイドロールで案内するだけで圧下を加えず、 凝 固完了後に铸片を大きな圧下ロールを用いて大圧下する方法力 特開平 8— 1 6 4 4 6 0号公報に記載されている （従来例 II) 。 On the other hand, in the unsolidified region of the piece, a method is used in which the piece is guided only by a guide roll and no reduction is applied, and after the coagulation is completed, the piece is largely reduced by using a large reduction roll. It is described in the gazette (conventional example II).
しかるに、 凝固完了後は、 小さな圧下量を加える場合でも、 大きな圧下力が必 要となり、 圧下機構が大形化したり、 大形のロールを必要とするなど、 設備費を 高騰させる。 また、 錶片のコーナ部温度の低下により圧延時に鎵片内部に割れが 発生する等の不具合が発生しやすく、 鍩片品質を低下させる。 However, after solidification is completed, even if a small amount of reduction is applied, a large reduction force is required, which increases equipment costs, such as the size of the reduction mechanism and the need for large rolls. In addition, defects such as cracks occurring in the inside of the piece during rolling due to a decrease in the temperature of the corner of the piece are likely to occur, and the quality of the piece decreases.
本発明は上記事情に鑑み、 従来の未凝固圧下法よりもさらに薄く圧下でき、 し かも銬片品質の良好な連続錶造方法および連続铸造装置を提供することを目的と する。 発明の開示 SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a continuous manufacturing method and a continuous manufacturing apparatus that can reduce the thickness even more than the conventional non-solidification rolling method, and yet have good piece quality. Disclosure of the invention
第 1発明の連続錶造方法は、 連続銬造装置において厚さ 4 0腿以下の铸片を製 造するために、 铸型出側厚さ 120 〜 5 0 mmの鐯片を凝固殻がある程度成長した後 、 铸片中央部で溶鋼が流動している未凝固状態で圧下し、 さらに続いて銬片中央 部の溶鋼の流動がなくなつたが完全には凝固していない半凝固状態においても圧 下することを特徴とする。 According to the continuous manufacturing method of the first invention, in order to manufacture a piece having a thickness of 40 thighs or less in a continuous manufacturing apparatus, a piece having a mold exit side thickness of 120 to 50 mm is solidified to a certain degree. After the growth, し the molten steel flows down in the unsolidified state where the molten steel is flowing at the center of the piece, and subsequently 銬 even in the semi-solidified state where the flow of the molten steel at the center of the piece has ceased but is not completely solidified. It is characterized by reducing.
第 2発明の連続錶造装置は、 出側厚み 120 〜 5 0讓の銬型の直下に 400 〜1000 腿の圧下しない非圧下領域を設け、 その下流において、 未凝固状態の铸片を圧下 する未凝固圧下ロール群を設け、 さらにその下流において、 铸片中央部の溶鋼の 流動はなくなつたが完全凝固する以前の錶片を圧下する半凝固圧下ロール群を設 けたことを特徴とする。 図面の簡単な説明 In the continuous manufacturing apparatus according to the second aspect of the invention, a non-roll-down area of 400 to 1000 thighs is provided immediately below a die having a delivery side thickness of 120 to 50 feet, and a non-solidified piece is lowered downstream thereof. A non-solidification reduction roll group is provided, and further downstream, a semi-solidification reduction roll group is provided to reduce the flow of the molten steel at the central portion of the piece but before the solidification is complete. BRIEF DESCRIPTION OF THE FIGURES
図 1は本発明の一実施形態に係る連続鐯造装置の概略構成図、 図 2は铸片温度 と変形抵抗力の相関関係を示すグラフである。
発明を実施するための最良の形態 FIG. 1 is a schematic configuration diagram of a continuous manufacturing apparatus according to an embodiment of the present invention, and FIG. 2 is a graph showing a correlation between a piece temperature and a deformation resistance. BEST MODE FOR CARRYING OUT THE INVENTION
図 1において、 1は錶型、 2は非圧下領域 2 Aの支持ロール、 3は未凝固圧下 領域 3 Aの圧下ロール、 4は半凝固圧下領域 4 Aの圧下ロールである。 In FIG. 1, 1 is a 錶 type, 2 is a supporting roll in a non-rolling area 2 A, 3 is a rolling roll in an unsolidified rolling area 3 A, and 4 is a rolling roll in a semi-solidifying rolling area 4 A.
铸型 1は、 対向する長辺が平行のものでも、 長辺間間隔が入側から出側に向つ て狭くなつているものでもよいが、 出側厚みが 120 〜 5 0匪のものである。 非圧下領域 2 Aは、 銬型 1の直下で、 400 ~ 1000匪の長さを有している。 この 間の铸片 Aは支持ロール 2でガイドされる力^ 圧下はされていない。 铸 type 1 may have parallel long sides facing each other, or may have a narrow interval between the long sides from the entry side to the exit side, but have a thickness of 120 to 50 bandages on the exit side. is there. The non-roll-down region 2A has a length of 400 to 1000 bandits just below the type 1. During this time, the piece A is not reduced by the force guided by the support roll 2.
銬型 1内に铸込まれた溶鋼は铸型 1内の一次冷却により冷却され、 銪片 A表面 に凝固殻 sが生成され、 続く支持ロール 2群でのスプレー水等による二次冷却に よりさらに凝固が促進されていく。 The molten steel injected into mold 1 is cooled by primary cooling in mold 1, and solidified shell s is formed on the surface of piece A. Coagulation is further promoted.
前記非圧下領域 2 Aに続く未凝固圧下領域 3 Aでは、 圧下ロール 3により未凝 固状態の铸片 Aを圧下する。 この未凝固状態では、 鐯片 Aの中心部は、 溶鋼が流 動しており、 小さな力で圧下していける。 また、 圧下力が小さくてよいから小径 のロールを用いて、 ロールピッチを小さくできるので、 溶鋼静圧によるバルジン グが生ずるおそれは少ない。 In the unsolidified rolling region 3A following the non-rolling region 2A, the unsolidified pieces A are reduced by the rolling rolls 3. In this unsolidified state, molten steel is flowing in the center of piece A, and it can be reduced with a small force. Further, since the rolling force can be small, the roll pitch can be reduced by using a small-diameter roll, so that bulging due to the molten steel static pressure is less likely to occur.
この未凝固圧下をしている間にも、 铸片 Aは自然に冷却していき、 凝固殻 sの 厚さは厚くなつていく。 そして、 圧下ロール 3による圧下で铸片厚さは薄くなつ ていく。 During this unsolidification reduction, the piece A naturally cools, and the thickness of the solidified shell s increases. Then, under the reduction by the reduction roll 3, the thickness of the piece decreases.
錶片 Aの両表面から生成していった凝固殻 s力接触する点が凝固完了点 6であ り、 未凝固圧下領域 3 Aの終点である。 凝固 The point of solidified shell s force contact generated from both surfaces of piece A is solidification completion point 6 and the end point of unsolidified rolling reduction area 3A.
前記凝固完了点 6に引き続いて、 それより下流において、 半凝固圧下領域 4 A が設けられる。 この半凝固圧下領域 4 Aは、 銬片 Aの中央部での溶鋼の流動はな いが、 铸片が完全には凝固していない状態である。 すなわち、 この半凝固状態は 铸片断面平均温度が 1200°Cもしくは铸片中心温度が 1350で〜 1400 以下にならな い領域であり、 凝固殻の平均温度が 1250〜1300での領域である。 この半凝固圧下 領域 4 Aでは、 従来考えられていた凝固状態の反力よりもはるかに小さな圧下力 で圧下できることが、 本発明者により見出された。 Subsequent to the solidification completion point 6, a semi-solidification reduction region 4A is provided further downstream. In the semi-solidification reduction region 4A, the molten steel does not flow at the center of the piece A, but the piece is not completely solidified. In other words, this semi-solid state is a region where the average temperature of the cross section is 1200 ° C or the central temperature of the half is 1350 and does not become lower than 1400, and the average temperature of the solidified shell is 1250 to 1300. The present inventor has found that in the semi-solidification reduction region 4A, the reduction can be performed with a reduction force much smaller than the reaction force of the solidification state conventionally considered.
すなわち、 図 2に示すように、 従来例 I Iで凝固銬片を圧下していた凝固圧下領 域では、 凝固殻平均温度が 1 100で程度であり、 変形抵抗力が 4 kg/讓 2であった
力 本発明における半凝固圧下領域 4 Aでは凝固殻平均温度が 1250〜1300でであ るので、 変形抵抗力は l kgZ腿2以下であり、 従来の約 1 Z 4以下の圧下力です むことになる。 That is, as shown in FIG. 2, in the conventional example II coagulation pressure area of the coagulation銬片was pressure at a degree solidified shell average temperature is 1 100, deformation resistance force is 4 kg / Yuzuru 2 met Was Power present invention in a semi-solid reduction region 4 A the solidified shell average temperature 1250 to 1300 Dedea Runode, deformation resistance force is at l KGZ thigh 2 or less, approximately 1 Z 4 following rolling force of the conventional-law and become.
したがつて未凝固圧下に使用していた圧下ロール 3と同様の小径の圧下ロール 4が半凝固領域 4 Aにおいても使用できるため口一ルビッチを小さく取れる。 し たがって、 生成し終えたばかりの凝固殻がバルジングすることがなく、 铸片のぜ い化域を外れた圧延温度 （1100°C以上） が確保できる高温領域で圧下するため、 錶片に内部割れが発生しない。 Accordingly, since the reduction roll 4 having the same small diameter as the reduction roll 3 used for the unsolidification reduction can be used also in the semi-solidified region 4A, a small mouth-to-litch can be obtained. Therefore, the solidified shell that has just been formed does not bulge, and it is rolled down in a high-temperature region where the rolling temperature (1100 ° C or more) outside the brittle zone of the piece can be secured. No cracks occur.
未凝固圧下領域 3 Aおよび半凝固圧下領域 4 Aでの圧下は小径圧下ロールを小 ピツチで配した圧下セグメントを昇降および傾動して行うように構成されている 。 そして、 圧下セグメントの昇降量および傾動量を変化させることにより未凝固 圧下および半凝固圧下により得られる銬片の厚さを自由に設定することができる また、 铸造速度の変動により、 凝固完了点 6が上流側へ移動したり下流側へ移 動し、 これに伴い、 未凝固圧下領域 3 Aの長さと半凝固圧下領域 4 Aの長さも変 動するが、 半凝固領域での変形抵抗は、 一挙に増大することはなく、 凝固完了点 が移動したとしても所定の厚みに圧下することができる。 The rolling in the unsolidified rolling region 3 A and the semi-solid rolling region 4 A is performed by raising and lowering and tilting a rolling segment in which small-diameter rolling rolls are arranged with small pitches. The thickness of the piece obtained by unsolidification reduction and semi-solidification reduction can be set freely by changing the amount of lifting and lowering and the amount of tilt of the reduction segment. Moves to the upstream side and the downstream side, and accordingly, the length of the uncoagulated rolling region 3 A and the length of the semi-solidified rolling region 4 A also fluctuate, but the deformation resistance in the semi-solidified region is It does not increase at once, and can be reduced to a predetermined thickness even if the solidification completion point moves.
なお、 図 1に示した連続鍩造装置は、 垂直型であるが、 湾曲型においても、 同 様の構成をとることができる。 産業上の利用可能性 Although the continuous manufacturing apparatus shown in FIG. 1 is a vertical type, the same configuration can be applied to a curved type. Industrial applicability
本発明によれば、 従来の未凝固圧下法よりもさらに薄く圧下でき、 しかも錶片 品質の良好な錶片を連続錶造することができる。
ADVANTAGE OF THE INVENTION According to this invention, it can roll down further thinly than the conventional non-solidification drafting method, and also can manufacture continuously a piece with good piece quality.
